T0 all wizom z't may concern Be it known that we, CHARLES N. MU'EIL- LER, a subject of the Emperor of Germany, und W1LLARD V. VAN DOREN, a citizen oi" the United States, both residents of Chicago, in i:he county of Cook and State of 1llinois, have invented a new and 1mproved Thermometer-Holder, of which thefollowing is a full, dem, andexact description.

This invention relates to an improveol device for holdi:ng a. thermometer and supporting a receptacle o1 cup with the thermometer extending thereinto and designed for special use in breweries, distilleries, chemical works and any kind of establishment where liquids me handled under couditions where the temperaure must be freuently taken, so tl1at When the device is let own into the liquid and izhe thermometer is'caused to show he temperature there0f, the liquid in the cup will retain the thermometer u1richanged for several minutes so as to permit the observer to dotermine the correct temperature of tlne l1quxd or to take the thermometer to 2 1 place where suilicient light can be had to conveniently read ic.

Another object of the invention is to provide a. holder for thermometers permiwhting one to ascertain ihhe exact temperature of liquids in dee tanks und. in tanks located in dark places; m which the thermometeris also protected from breakage and-in which means aie also provided for removably holding the therm'ometer in position so as to permit .it to be replaced by another thermometer varfing in its scmle er typo of indexmg as wel as in size.

With the above and other objects in view, the invention resides moxe particulmcly in the peculiar combination und arrangemenf of parts .which will be illustrated as 2i preferred e'mbodiment in the' accompanying drawings and described in the specification.

Reference is to be had to the accompanying drawings forming. a part of this specification, in which similar characters of reference indicate corres&onding parts in all the views, and in whic Figure 1 is a vertical secti0nal" view of the imj1roved thermometer holder with a. thermometer held therein; Fig. 2 is a. lan view of the dmice; und Fig. 3 is a cross sectional view taken on the line 33 of Fig. l.

In the illustrated embodiment of the invention, the improved holder is shown as comprising a cup 01 receptacle 10 proferabl y of copper 0x otlxer heat-conducting mater1al of some degree of flexibilitjf, in which aro supported a plurality of wires or rods and attached to the interior Wall of the cup' 10. 'lhe rods 11 forming the fmmework .are hold in rigid spaced relation by means of a plurality of apertured rings 13 soldered 01' oiherwise connected ito the rods against longitudinal displacemoht thereon, as shown m 14, und. disposed at n mid-p0int and near tl xe ends o:l the IO(1S respectively, the lower rmg, however, being disposed sligl1tly nbove the upper edge of the receptacle, und each hagng apertures through whicli the rods exten Tl1e aperture 15 of theintermedinte ring rece1ves a thermometer 16 comparatively snugly theretl1rough, while the aperture of the upper ring receives a rulober or other compressible insulating sleeve 17 and the aperture of the lower ring a similar sleeve 18 through which the thermometer is snugly engaged und supported tbo obviate breakage ir'om shock, also i:o prevent the heat of the metal afiecting the temperatuie shown on the thermometer which hs its bulb 19 immersed well dowri into the liquid contained in the cup after the device is let down into the tank and withdrawn. For tbhis latter purpose a bail 20 is pivoted as shown at 21 to apertured ears ca rried by the flanged portion 22 of a cap 23 which is, through the instrum;enlzaliizy of tl1o flimged portion, attacl1ed to tho upper ring l3 as b means of fastening screws 24. Tl 1is cap fu ly incloses tl1e upper end of the thermometer and is also preierably of copper or similar material, to protect the thermometer from breakage but can be readily' removed, as will be apparent, for the purpose of changing thermomelers. A chain or other flexible connection 25 is attached to the bail for the purposo of 10W- ering the device into a tank or vat containin the liquid, the temperature of which is to e ascertained.

Thus it will be seen thal; a thermometer held in a device such as descrioed will be protected from breakage and .may be dropped into a tank or any othex kind of liquid container so asto afiect the expansion of the indicating fluid and afiect the read.ing of the thermometer. In devices
